2. Description of the Prior Art:

In current use are numerous embodiments of automobile washing unitswhich have in common a mode of operation wherein the automobile is urgedalong a path of movement in association with different apparatusstrategically located and designed to clean a different part of theautomobile. Alternatively, the washing unit is set into a movable frame,usually on tracks, and the automobile remains stationary inside thewashing unit while the latter moves thereover. Consistent with thepopularity and proven commercial acceptance of these units, there is acontinuing effort by equipment manufacturers to provide improved carcleaning apparatus, particularly that designed to clean the automobileside windows which are only partially cleaned by prior art brushes inthat only the central portions of the windows are contacted by the brushand not their peripheral areas. Another problem has been to provide abrush which will completely clean the front, side panels, fenders andrear of the automobile regardless of its shape and dimensions. Forexample, if the design of the automobile is characterized by having anumber of pronounced indentations, such as in the front of the car, theprior art brushes are not adapted to compensate for these indentationsand as a result the body is not completely washed at that portion.

SUMMARY OF THE INVENTION It is therefore among the principal objectivesof the invention to provide an improved automobile side window washerand body washer overcoming the foregoing and other short comings of theprior art. In accord with the invention there is provided, for use inacar or automobile washing unit in the operation of which the washingunit surrounds the automobile and moves along a prescribed path, therebyassociating the automobile with various apparatus contained on thewashing unit for cleaning different parts of the automobile, incombination a side window washer and a front, side panel, fender andrear body washer.

The side window washer includes at least one brush centrifugably mountedon a pivotal overhead support which yieldably extends into theautomobile during its path of movement so that the brush, during acleaning interval, makes cleaning contact with the automobile and, moreparticularly, as the washing unit moves past the automobile, the angularorientation of the brush is such that the brush has a wiping strokediagonally across the automobile side window so that the successiveportions of the window coming into contact with in complete contactingrelation therewith.

The body brush includes at least one brush rotatingly held in a supportframe pivotally mounted on an overhead support, which is itselfpivotable in dual crossdirecn'on by virtue of its dual pivotalarrangement with the washing unit frame, and which brush initiallyextends directly in front of the automobile during its path of movementso that the brush, during its cleaning interval, makes cleaning contactwith the automobile and, more particularly, as the washing unit movespast the automobile, the pivotal arrangement of the brush and overheadsupport is such that the brush is continuously moving in aplane verticalto the automobile and has a wiping stroke adjustable to the shape anddimensions of the automobile.

FIGS. 9, l0 and 11 are diagrammatic top plan views sequentially showingthe movement and washing action of the body brushing during the path ofmovement of the washing unit along the body of the automobile.

DESCRIPTION OF THE SPECIFIC EMBODIMENTS Referring now to the figures indetail, and particularly to FIGS. 1 to 4, there is illustrated anautomobile washing unit 10 having a frame 12 to which is mounted viasuitable supports to be described, a pair of opposing side windowbrushes 14 and a pair of opposing body brushes 16 for washing the front,side panels, fenders and rear of an automobile 18. The washing unit isof a conventional design, wherein the automobile to be washed remainsstationary, while the auto washing unit surrounds the automobile andpasses thereover, thereby associating the automobile with the variousapparatus contained on the washing unit for cleaning different parts ofthe automobile. Usually, this type of unit is rideable on tracks andduring its operation, an automobile is driven into the washing unit to apoint where an electric eye type of signaling device is provided, andwhose actuation, thereby automatically starts the washing and movingoperation of the washing unit.

Describing first the side window washers 14, there is provided connectedto the horizontal cross member 20 of frame 12, a pivotally mountedL-shaped brush support 24 which, at approximately the juncture of itslegs 24a and 24b, has an appropriate bracket for mounting a motor 26which is operatively arranged to centrifugally drive the brushes 14.Specifically, the brush support leg 24b will be understood to be ahollow housing having appropriately entrained, on supporting sprocketstherein, an endless driving chain operatively connected to the motor 26at its input end, and at the output end connected to the support shaft28 of the brush 14. As generally understood, rotation of the shaft 28produces corresponding rotation of the body of the brush 14,diagrammatically illustrated in the drawings, but fabricated of numerouslengths of stringy yarn such as is conventionally used, for example, inmops, which are connected radially to, and dangle from, the brush mount30. Thus, when the shaft 28 rotates the brush mount 30, the danglinglengths of stringy yarn will be propelled outwardly by centrifugalforce, thereby achieving the propeller-type cleaning motion of the brushas illustrated by dotted lines in FIGS. 1 and 4. The opposing brushesare rotated so that one operates in a clock-wise direction and the otherin a counterclock-wise direction.

According to a critical feature of the invention, the brush support legs24a and 24b are joined so that they subtend an obtuse angle X ofpreferably 155. By virtue of this orientation, the brush mounted tosupport leg 24b is itself disposed at an acute angle Y of 25 withrespect to the vertical plane of the support leg 24a. It has been foundthat by this particular angular orientation that the brush achieves awiping stroke diagonally across the automobile side window 19, such thatsuccessive portions of the window coming into contact with thecentrifugally whirling brush are in complete contacting relationtherewith. In other words, in contrast to the prior art, the entirewindow at the point contacted by the brush is washed, i.e., the central,as well as peripheral portions of the window.

As earlier mentioned, the overhead support 24 is mounted to horizontalmember 20 by means of a pivot 40 which will allow for movement of thebrush support back and forth depending on the width of the automobilebeing washed. This brush support is adapted to be self-adjusting bymeans of a tension spring 42 connected between vertical frame member 44of the washing frame 12 and the brush support leg 24a. Thus, when theframe 12 with its attendant automobile cleaning parts move over theautomobile, the brush will extend into the automobile during the path ofmovement of the frame and depending on the width of the automobile thepivotally mounted support will be displaced outwardly in the directionof the arrow 0, and when the washing operation has been finished and theautomobile driven out, the tension spring 42, by.virtue of itsself-adjusting nature, will bring the brush support 24 back to itsoriginally, normally, oriented position.

Referring now to FIGS. 1 and through 8, inclusive, there is shown arotary car body washing brush 16 which is designed specifically to cleanthe car front, side panel, fenders and rear of the car body. Asmentioned earlier, the car wash unit is of the type that moves over thecar while the latter is in a stationary position. Thus, the brush 16, inits starting cleaning position, is located in a position operative tomake cleaning contact with one-half of the front of the car; whereas,the subsequent cleaning position of the brush 16 is one in which it isboth in advantageous position in orientation to make cleaning contactwith the fenders, side panel and one-half of the rear of the car, aswill be described further in detail subsequently.

The rotary brush 16 will be understood to be generally of conventionalconstruction and made of usual materials which provide a cleaning body50 appropriately mounted on a central, longitudinal shaft 52, the lowerextending end 54 of which is conventionally accommodated in a bearing 56affixed to a pivotal support 58. The upper shaft end 55 is connected toa drive shaft of a motor 62 which is operatively effective to power thebrush 16 in rotation.

Serving as a mounting for the brush is a C-shaped support generallydesignated 64 formed by an upper leg 64a, a lower leg 64b and anintermediate interconnecting leg 64:), the brush 16 being appropriatelyjournaled for rotation in the front opening of the support 64, betweenthe upper and lower legs 64a and 64b. The motor 62 is advantageouslysupported on the upper leg 64a with its drive shaft depending therefromthrough an appropriate opening in the upper leg 64a into a positionadjacent the upper shaft end 55. The connection between motor driveshaft and rotarizable brush 16 is conventional andneed not be furtherdescribed here, the invention lying elsewhere, as will be readilyapparent.

The C-shaped support 64 is in turn pivotally connected by means of apivot through connecting member 71 at the juncture of the upper leg 64aand connecting leg 64c, to an overhead support bar 72. Similarly,another support bar 74 parallel to support bar 72 is also pivotallyconnected to the C-shaped support 64 at a position intermediate saidsupport bar 72 and motor 62 and connected to support leg 64a by means ofa pivot 76 through connecting member 73. In turn, the support bars 72and 74 are pivotally connected to the overhead, horizontal cross member20 by means of pivot pins 78 and 80 respectively, in suitable pivothousings 81 and 83,- respectively. Further, in turn, the entire bodybrush assembly 82 is connected to pivotal means 84 consisting of a pivotpin 86 journaled for rotation in a pair of opposing end plates 88 joinedby a connecting plate 90. A conventional hydraulic cylinder 91A actingin association with a return spring 93 supplies the moving powerlengthwise of the car 18, for the pivotal means 84 and thereby the bars72 and 74. Pivotal means 84 are self-adjusting as will be seen by thedimensions of the car being washed. Similarly, a conventional hydrauliccylinder 91B (FIG. 6) supplies moving power directly to bars 72 and 74widthwise or transversely of the car 18. Thus, looking at FIGS. 5 and 6specifically, the pivotal actions of the overhead support bars 72 and 74are operable at right angles to the pivotal action of the entireassembly 82. In other words, the body wash brush is pivotal in dualcross direction by means of the aforesaid pivotal arrangements justdescribed, the power cylinders 91A and 9113 being controlled byconventional means.

As earlier described, C-shaped support 64 is pivotally mounted tooverhead support bars 72 and 74.

' as follows: As an example, looking at FIG. 5 when the brush 16 is inthe vertical starting cleaning position (shown by solid lines), it is inthe front 21 of the car. By virtue of the self-adjustable nature of thepivot means 84 the brush is in a position to compensate for the lengthof the car, as well as its particular design features, by beingpivotally movable either in a direction towards the car or outwardlyfrom the car. In other words, if the front of the car has a pronouncedindentation, in contour the pivotal manner by which the brush 16 issupported for movement in dual cross-direction will compensate for thisby moving the brush into the contoured indentation thereby cleaning thatparticular spot completely. Thus, conversely, if the front of the car isprovided with a projection, similarly the pivotal action of the brushwill compensate for the projection by allowing the brush to be displacedforwardly of the car. The width wise dimensions of the car arecompensated for by the hydraulically operated pivotal action of thesupporting bars 72 and 74. This is shown by the relative dotted linepositions of FIGS. 6 and 8.

Referring now to FIGS. 9 through 11, the cleaning action of the bodybrushes is diagrammatically shown. They operate in a counter direction,one clock-wise and the other counter-clock-wise. The frame of the autowashing unit (not shown) is moving in the direction of the arrows, fromfront to back, along the front sides and rear of the stationaryautomobile 18. As shown in the initial starting position, the rotarizingbrushes 16 (shown by dotted lines) are in a position in the front F ofthe automobile. As the brushes continue to rotarize, they arehorizontally movable along the front end of the auto until they come tothe end of the front portion, then the brushes turn at a substantiallyright angle as shown by dotted lines and proceed to wash the fenders andside panels of the car until they come to the rear R of the automobilewhen another substantially right angle turn is made and the rear end ofthe auto is washed. This is another feature of the invention, and thisis that the combined action of the pivotal arrangements of the C-shapedsupport, the overhead support bars and the brush body assembly providesfor this right angle brush cleaning direction at the comers of theautomobile. Thus wasted motion is avoided and the brushes arecontinuously in contact with the surface of the automobile body.

In accord with the invention, therefore, there has been just describedan improved automobile washing unit which provides for complete cleaningaction with respect to the parts intended to be washed thereby; the sidewindow brushes completely wash the side windows and the body brushescompletely wash the front, side panels, fenders and rear of theautomobile body.
